Reclamation of Wellington Harbour
Reclamation of Wellington Harbour started in the 1850s, in order to increase the amount of usable land for the then new City of Wellington. Flat land plots in the early city were scarce, with little room for public buildings and parks, as well as inadequate dockside areas for shipping.
